v0.2.4 is coming along slowly but surely and I'm looking forward to moving away from the technical end of things soon. All 9 Character bases have been updated to the physics system (4 of the 13 in the cast are shared) with the test going well. Dialogue system has been updated to support animal crossing-style vocals and I updated the cutscene system to work more smoothly with cinemachine and timelines. Further AI improvements are going to have to wait on v0.2.5 which will start in March and will probably be out sometime in April.
No, rea, bella and thorn's voices were not ai generated and were recorded from voice actors and with the background noises editted out in audacity however its not feasible to record voices for every line of dialogue in the cutscene parts of the game. The voice acting clips will remain during the gameplay sections.
